What each ingredient does

Stock
The main liquid being clarified, so its clarity and flavor define the finished result.
Egg white
Whips into a frothy mass that traps cloudy particles, which are then removed when the stock is strained.

The step that matters

Allow the stock to boil once, then remove from heat. The egg white raft must set and hold impurities. Boiling it hard or repeatedly breaks the raft apart, releasing particles back into the stock and making it cloudy.
